CORNQ-PLANTER.

SPECIFICATION forming part of Letters Patent No. 429,532, dated June 3,1890.

Application filed February 6, 1890. $erial No. 339,376. (No model.)

To all whom it may concern:

Be it known that I, EVERELL A. JOHNSON, a citizen of the United Statesof America, residing at Brady Island, in the county of Lincoln and Stateof Nebraska, have invented certain new and useful Improvements inCorn-Plane ers; and I do hereby declare the following to specification.

My invention relates to corn-planters; and it consists in the improvedconstruction hereinafter described and set forth, whereby a simple andefficient arrangement is provided that is serviceable and positive inoperation.

In the accompanying drawings, forming part of this specification, Figure1 is a plan view of a corn-planter embodying my improvements. Fig. 2 isa rear elevation there- 'of, and Fig. 3 is a sectional View.

The frame consists of a transverse bar a, to which a bar I) is rigidlyconnected by means of converging braces c c. The seed-hoppers A arelocated on the bar a, adjacent to each end of the same, and have ontheir under sides a plate or guide, in which plays a transverse bar B,the end portions of which constitute the seed-slide of the hoppers. Thebar a has projections e 6, against which lugs f, depending from theunder side of the bar B, contact, in order to limit the reciprocationsof said bar. -Centrally mounted upon the upper side of the bar B is anarm 0, the end portion 9 of which is bent horizontally.

The hoppers A carry on their rear sides boxes h, which are bolted inposition and within which bears a transverse shaft or axle C, of alength twicethe width of the space between the hoppers, and on thisshaft, outside of but adjacent to each hopper, is keyed a maincarrying-wheel D, the spokesz' of which have their ends projectingbeyond the periphery of the wheel in order to secure proper tractiontherefor. An annular ring j is secured on the sides of the spokes, andis provided with a cam-shoulder k, guarded by parallel ribs Z.

a horizontal extension m, upon which is mounted a short vertical platen, having a vertical slot 0, in which plays a web 19, at-

tached to a horizontal rod q, the inner ends thereof being bent toengage the hook of the arm, while the outer end of arod plays through avertically-perforated ear 0" on the outer edge of the hopper. Each ofsaid rods is provided over each hopper and adjacent to the verticalslotted plate with a block 8, to which is attached one end of a coiledspring t, the other end of which is connected to the adjacent ear rorother fixed part of the machine.

It will be noted that the cam-shoulders on the carrying-wheels arerelatively located diametrically opposite to each other, and that theposition of the rod is designed to be such thatone end of the same is tobe engaged by either of the cams and vibrated twice for each completerotation of the carrying-wheels.

In operation the oppositely-located cams successively contact with therespective ends of the rod, each of the said ends being guided upon thecam by the parallel guide-strips before mentioned. Now as the cam forcesthe rod to one side the spring of the other rod, which has beenpreviously distended by the opposite cam, acts to shift its rod ontward,and through its hook engagement with the arm shifts the seed-slide inthe same direction, a corresponding operation taking place and the slidemoved in the reverse direction by the other cam. The outer ends of theshaft O carry marker-arms H, which revolve therewith to score the earthand indicate the 10- verse bar, seed-hoppers located on the same,

Each hopper carries at its upper inner edge together with a main axle,carrying-wheels provided with cams, a seed-slide bar reciproeating inguides below thehoppers and carrying centrally a vertical arm providedwith a bent end, and independent rods playing in guides located on thehoppers and engaging said arm and actuated from the cams of thecarrying-wheels, substantially as set forth.

2. The combination, in a corn-planter, of the supporting-frame providedwith a transverse bar, seed-hoppers located on the same.

at each side thereof, together with a main axle, carrying-wheelsprovided with cams, a seed-slide bar reciprocating in guides below thehoppers and carrying centrally a vertical arm provided with a bent end,independent rods playing in guides located on the hoppers and engagingsaid arm and actuated from the cams of the carrying-wheels, and bladesor EVERELL A. JOHNSON.
